Selling a yacht is tricky when you’re in jail. Just ask Dennis Kozlowski, the former CEO of Tyco International, who’s serving at least seven years in prison for looting his company of $600 million. Kozlowski, whose lavish pre-jail lifestyle included a Fifth Avenue apartment, Nantucket and Boca Raton homes, and a Jimmy Buffett performance at his wife’s birthday party, has been trying to unload his 130-foot sailing yacht Endeavor for a year (price: $17.3 million). Built in the thirties to compete for the America’s Cup, it costs him over $1.5 million a year in upkeep, sailing around with its crew of nine, a sort of Flying Dutchman for billionaires. During the first weekend of April, it was in St. Barts’ “bucket regatta.” (New York real-estaters Harry Macklowe and Louis Cappelli also raced.) Every night during the regatta was an open house, with free booze and food and guided tours of the spacious interiors, which include rare sailing-yacht luxuries: a bathtub and fireplace.
